TABLE 1.
Performance of ELISA comprising rTR18, rKR95 and rK39 versus DAT
| Antigen(s) | Total no, % (n = 104) | No. with DAT titer of <6,400, % (n = 23) | No. with DAT titer of >6,400, % (n = 81) | % Specificity (n = 48)a |
|---|---|---|---|---|
| rTR18 | 34 (33) | 4 (17) | 30 (37) | 94 |
| rKR95 | 66 (63) | 10 (43) | 56 (69) | 89.5 |
| rTR18 and rKR95b | 72 (69) | 12 (57) | 60 (74) | 83 |
| rK39 | 82 (79) | 14 (61) | 68 (84) | 87.5 |
| rTR18, rKR95 or rK39b | 87 (84) | 16 (70) | 71 (88) | 83 |
a
Specificity was calculated against DAT-negative endemic controls.
b
Theoretical estimate based on the combined sensitivity of the antigens.
